## 0.7. Cross-References

If a cross-reference is to a single word -- for example, a command name like this: tar -- the cross reference is probably to an article that introduces that command. Cross references to phrases -- like this: from a parent process to child process -- are to an article that explains more about the concept or problem printed in gray.

Cross references don't necessarily give a complete list of all articles about a topic. We've tried to pick one or a few articles that give the best information. For a more complete list, use the Index.
